TechCrunch’s annual Startup Battlefield 200 competition sees hundreds of companies from around the world compete for the chance to get in front of VCs and the international tech community at the Disrupt conference each year.
This week, nine early-stage Korean startups participated in the technology conference DETO 2026 in Seoul to qualify for next year’s Startup Battlefield 200.
These startups operate across deep technology sectors such as healthcare, fintech, energy, semiconductors, and AI. All nine startups are aiming to enter the U.S. market as part of broader international expansion plans.
Voinosis, which develops an AI that detects changes in brain health through voice analysis, won the competition. The other eight startups are listed alphabetically below.
Voinosis develops AI tools that analyze speech patterns such as pitch, pauses, rhythm, and response times to detect changes related to brain health. Each audio check takes less than 5 minutes.
The company says its technology has been tested in Greek, Japanese and English, and the product does not require separate training for each language. In a clinical study involving 146 participants, the company claims its technology achieved 88% accuracy in screening for potential cognitive problems.
Voinosis targets hospitals, senior living facilities, insurance companies, and individual consumers. The company also plans to link voice checks with cognitive training, assessment and treatment by medical professionals.
The startup was founded by Grace Shin, who worked as an ENT surgeon for over 25 years. The startup is currently raising a Series A round of funding and has already secured a Korean pharmaceutical company as a strategic investor.
Seoul-based Awesome Lab makes ThermoFlux, a heating system that uses water electrolysis and ionization to generate heat. The system can manage heat generation for buildings, water supplies, and industrial processes. The company says its technology can reduce energy consumption and carbon emissions.
To expand internationally, Awesome Lab takes a different approach in each market. In the US, the company plans to supply core OEM modules and work on product development with boiler, water heater, and HVAC companies.
Crosshub helps travelers and international visitors verify their identity and set up their payment methods abroad. Its platform, IDBlock, combines identity verification and payment services using self-sovereign identity (SSI) and zero-knowledge proofs.
The company says its platform helps users prove their identity across borders without sharing unnecessary personal information. Crosshub is also integrating this technology with payment systems to improve access to financial services for travelers.
DeepFusion AI has developed a 4D radar-based imaging system with additional sensors for autonomous mobility, robotaxis, maritime surveillance, and defense applications. This system combines RF sensors with radar and lidar to detect objects, movement, or distance without direct line of sight. All sensors are likely packed into a single customizable unit.
EFLOW develops specialized motors that can generate more torque or rotational force in less space for use in robots, drones, satellites, and other mobility applications. The startup is also developing actuators that control the movement of robot joints.
Otition Medical manufactures two medical devices. One is specialized for measuring body temperature, and the other can take images of the ear canal and analyze the eardrum. The company said its AI was trained using about 55,000 images of eardrums, and the device has received medical certification in South Korea.
Riibotics says it can have robots in warehouses within a day. Riibotics wants to reduce warehouse implementation costs by streamlining the setup of infrastructure setup, warehouse mapping, system integration with custom middleware, task programming, safety checks, and more.
Ulsan-based semiconductor startup Ternell is developing a new type of memory to help reduce power consumption in AI chips.
Unlike traditional two-state memory, Ternell’s T-SRAM system adds a third state for more efficient data storage. Turnell, founded in 2019 by former Samsung Electronics engineer Kyungrok Kim, reports that tests using 28-nanometer chips showed 33% to 102% more memory capacity per area compared to traditional SRAM, and 55% to 71% less energy needed to access data.
Testbank is a Korean edtech startup that develops Solve, an app that converts printed learning materials such as workbooks and test prep books into interactive digital versions.
The startup uses AI to identify question and answer spaces within publishers’ PDF files while preserving the original layout. With Solve, you can write your answers directly on the page and it will be graded automatically.
